Is 103/59 consider low blood pressure?

I am currently 12w 6d pregnant and today I woke feeling sick. I think my blood sugar had dropped as I felt my hands weak. Is it normal? 
Sorry I'm updating**
I woke up feeling sick this morning.. I felt weak from my arms and i felt like I had indulged myself with a lot of sugary food which I hadn't. That's why I am guessing my blood sugar had gone down. I ate some protein and the feeling went away about an hour later I took my blood pressure and it was 103/59. I know both things are completely different but I'm just wondering if all this is normal during pregnancy since I don't get to see my doctor Til late next week and I'm waiting for a nurse to call me back so I can explain this to them. Sorry if it all sounds confusing and thanks in advance!
